DISPENSING DEVICE FOR CARBONATED BEVERAGES.

Specification of Letters Patent. Patented B1 18, 1919,

Application filed April 1. 1918. Serial No. 225.908.

T 0 all whom it may concern:

' Be it known that I, CHARLES M. EARL, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and useful Dispensing Device for Carbonated Beverages, ofwhich the following is a specification.

This invention relates to dispensing devices for carbonated beverages,more particularly ginger ale. 7

It is the object of the invention to facilitate and expedite thedispensing of such highly carbonated beverages as ginger ale byproviding means to quickly relieve the gas pressure under which suchbeverage is charged when stored in containers to reduce the effervescenttendency of the liquid when drawing it from the container into servingreceptacles, and to accomplish this result by spreading the dischargingagitated beverage in a thin film upon the walls of an aerating chamberso that the carbonaceous gas will be readily liberated to escapeallowing the mixture to settle and liquefy preparatory to finaldischarge from said chamber.

In attaining this object, the invention contemplates associating a gasseparating or aerating chamber in a -unitary relation with a valvecontrolling delivery from the container thereto, said chamber having anoutlet for the discharge of the beverage into serving receptacles, andthe unit being adapted for direct connection to the container whereinthe beverage is stored under gaseous pressure.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, wherein,

Figure 1 is a view in side elevation of the dispensing device applied toa common form of beverage container.

Fig. 2 is a vertical sectional view of the device.

Fig. 3 is a sectional view, the plane of section cutting the gasseparating chamber as indicated by line 33 of Fig. 1.

In these views the reference character 1 designates a valve and 2 thevalve casing. the latter having its lower or inlet end screw-threaded,as indicated at 3 for connection with the outlet pipe 4 of a tank orbeverage container 5. It is to be understood that the beverage withinsaid container is under pressure of a carbonaceous gas and isimpregnated therewith.v suitable type of valve will serve the purpose ofthe discharge from the container. Surmounting the valve casing 2 is amixture aerating or sep..rating chamber comprising a base 6 integralwith said casing, a top 7 and a glass cylinder 8 clamped between saidtop and base by a plurality of bolts 9, the extremities ofwhichperipherally engage said top and base exteriorly of the cylinder.The top 7 has a central upwardly embossed dome portion 10 in which areformed a series of outlets 11 for the escape of gas liberated Withinsaid separating chamber. The b ase 6 is formed with a liquid dischargespout 12, having the customary down-turned outlet. Between the cylinder8 and the base and top, packing rings '13 are interposed to insureagainst leakage at the joints.

The upper or discharge end of the casing 2- is threaded for engagementwith the lower end of a stand pipe 14; which rises centrally within theseparating chamber and carries on the upper portion thereof a rotativedischarge nozzle formed by a plurality of hollow arms 15 radiating froma collar 16 journaled on the pipe 14 and into which the inner ends ofaid arms are screw-threaded. The hollow arms communicate with an annularspace 17 formed interiorly of the'collar 16 and through said space and aseries of passages 18 with the pipe 14. Each of the arms 15 is providedwith a row of jet orifices 19 at one ide thereof, the arrangement ofsaid orifices in the several arms corresponding so that re-action of thedischarging jet-s upon the nozzle will induce rota tion thereof. Anannular shoulder 20 upon the pipe supports the nozzle, and a nut 21threaded upon a shouldered stud formed on the closed upper end of thepipe 14: and engaging the collar 16 holds the nozzle against axialdisplacement from said pipe.

In the use of the above described construction, when the valve 1 isopened, the pressure of gas in the containers 5 will force the contentsthereof up through the pipe 14, and through the outlets 18 and space 17into the arms 15, from which it will escape through the orifices 19. Inleaving the nozzle arms the carbonated liquid will be thrown in a largenumber of small jets upon the cylinder 8, being uniformly distributed inthe horizontal plane of said jets due to the rotation of the nozzleinduced by the reaction'of the jets upon the arms. Thus the liquid flowsdown the interior surface of the cylinder 8 in the form of a thinfi]m,and I in this form the carbonaceous gas is readily liberated andquickly escapes from the separating chamber by Way of the outlets 11.Being thus freed of its gas, the beverage as it discharges through thespout 12 is free from any efl'ervescent effect and may be served atonce. WVhat I claim is:

1. A beverage dispensing device comprising a gas separating chamberhaving separate gas and liquid outlets, and a liquid discharge memberrotatively mounted therein for uniformly spreading the liquid upon theWall of said chamber.

'2. A beverage dispensing device comprising a gas separating chamberhaving separate gas and liquid outlets, and a liquid discharge membermounted therein and rotatively actuatable by the re-action of thedischarge for spreading the liquid upon the 'wall of said chamber.

A beverage dispensing device comprising a gas separating chamber havingseparate gas and liquid outlets, a liquid discharge nozzle thereincomprising aplurality of radial arms having outlets in correspondingsides thereof, and a delivery pipe for respectively having gas andliquid outlets,

and a valve controlling delivery to said chamber.

. 5. A beverage dispens ng device compris- .ing a gas separating chamberhaving scpa rate gas and liquid outlets, a pipe extending upwardly intosaid chamber for delivering a carbonated beverage thereto, said pipehaving a series of laterally opening outlets in its upper portion, and adischarge member journaled upon said pipe comprising a plurality ofradial tubular arms having correspondingly directed jet openings and ahub carrying said arms, having radial passages alined with the arms andopening into an annular space adjacent the upwardly extending deliverypipe and communicating with the outlets of said pipe.

In testimony whereof I sign this specification.

CHARLES M. EARL.
